Correct. As a matter of fact we use the current interpreter's knowledge 
also for introspection and serialization.

Right, having a working interactive C++ interpreter would also help for 
a debugger, as you said assuming that the symbols "are there". Function 
calls will be possible, too; you could also create objects in the 
interpreter stack and evaluate them.

So - are you interested? :-)

Cheers, Axel.
